The user wants me to create a full-screen flocking simulation (boids) with:
1. Separation, alignment, and cohesion behaviors
2. Boids drawn as oriented triangles
3. Smooth steering
4. Flee from mouse cursor
5. All in a single index.html file with inline CSS and JS
6. No external resources

This is a classic boids simulation. I'll need to:
1. Create a full-screen canvas
2. Implement the three boid rules (separation, alignment, cohesion)
3. Add mouse avoidance
4. Draw boids as oriented triangles
5. Make it smooth and performant

Let me write this as a single HTML file with everything inline.

I'll create a full-screen boids flocking simulation with all the requested features. Let me write this as a single self-contained HTML file.

The user asked me to create a full-screen flocking simulation of boids with specific features:
1. Separation, alignment, and cohesion behaviors
2. Drawn as oriented triangles
3. Steer smoothly
4. Flee from the mouse cursor
5. All in one self-contained index.html file

I've created the file with all these features. Let me verify it was created correctly by reading it back or checking if the file exists.

I've created a full-screen boids flocking simulation at `/workspace/index.html`. Here's what it includes: **Features:** - **Separation**: Boids steer to avoid crowding neighbors - **Alignment**: Boids steer to match the average heading of neighbors - **Cohesion**: Boids steer to move toward the average position of neighbors - **Mouse avoidance**: Boids flee from the cursor with stronger repulsion when closer - **Oriented triangles**: Each boid is drawn as a triangle pointing in its direction of motion - **Smooth steering**: Force limits and gradual acceleration changes - **Trail effect**: Semi-transparent fade creates motion trails - **Edge wrapping**: Boids wrap around screen edges **Technical details:** - 150 boids with cyan/blue coloring - Configurable weights for each behavior - Mouse influence radius visualization (subtle red circle) - Responsive to window resizing - Touch support for mobile devices - No external dependencies - runs fully offline Open `index.html` in a browser to see the simulation. Move your mouse cursor near the flock to watch them scatter and flee!
